Introduction to Snap Action, Limit Switches

The various types of snap action and limit switches serve many useful functions and applications in an array of industries ranging from automotive to home appliances. These types of switches can be found in a variety of components and in many different designs and configurations. Generally, snap action, limit switches are mechanical switching devices, but can also be constructed of plastic or other materials.

What Are Snap Action, Limit Switches?

Snap action and limit switches are mechanical switches that are activated when a plunger is mechanically and quickly forced into a switch, causing a metal contact to move from one position to another and, ultimately, activates or deactivates the switch. The rapid movement of the metal contact causes a sudden, distinctive "snap" sound, thus giving the switch its name. Generally, the metal contacts remain in the closed or open position until an opposite force is applied.

The 604HE162

The 604HE162 is a snap action, limit switch designed to meet a wide range of demanding applications. This rugged and reliable switch is designed to resist abrasion, corrosion, shock, vibration and extreme temperatures while providing a long life span. Ideal for applications where accuracy and repeatability are of the utmost importance, the 604HE162 switch provides accurate and reliable switching action even during the most extreme conditions.

604HE162 Application Field and Working Principle

The 604HE162 snap action, limit switch provides an accurate and reliable way to activate and control electrical circuits in a variety of demanding applications. This type of switch is perfect for commercial and industrial applications, including automotive, home appliances, robotics, hydraulic/pneumatic systems and more.

The 604HE162 switch features an adjustable travel length and operate force, making it suitable for a wide range of feedback requirements. When the plunger is mechanically pushed, a metal contact is forced against an electrical wire, completing the circuit. This contact is typically mounted onto a flexible spring that allows the contact to snap back into its original position when the plunger is released. This snap-action allows the 604HE162 switch to provide an accurate and repeatable switching action.

The 604HE162 snap action, limit switch utilizes a double-break mechanism to ensure accurate and repeatable contact breaking. This double-break configuration helps to dramatically minimize any arcing or spark-over when switching currents and voltages. Also, the 604HE162 switch can be easily contained within an enclosure suitable for the environment the switch will be operating in, such as dust-proof, waterproof or other specialty enclosures.

Conclusion

The 604HE162 snap action, limit switch is ideal for applications requiring accurate and reliable feedback. Utilizing a double-break mechanism, the 604HE162 switch is able to provide accurate switching action in even the most extreme conditions. This switch is suitable for a wide range of applications, including automotive, home appliances, robotics and more.
